Abstract

Das Verfahren dient zum permanenten, berührungslosen Messen von Stromstärken an einer Einzelleiter- oder Mehrleiter-Ummantelung (6), indem a) um die Ummantelung (6) eine Manschette angelegt wird, sodass sie die Ummantelung (6) mit ihren inliegenden Leitern (7) umschliesst, und in welcher Manschette um ihren Umfang verteilt mehrere Magnetfeldsensoren (8) angeordnet und ausgerichtet sind, b) die aufgrund des in den umschlossenen isolierten Leitern (7) fliessenden Stromes erzeugten Magnetfelder durch die Magnetfeldsensoren (8) vermessen und als elektronische Daten erfasst werden, c) mittels zuvor empirisch ermittelter Algorithmen zur mathematischen Beschreibung der Relation zwischen Stromstärken in einzelnen Leitern eines Leiterbündels und den von ihnen erzeugten Magnetfeldern die effektiv fliessenden Stromstärken in den einzelnen ummantelten Leitern errechnet werden, d) die ermittelten Stromstärken als Daten-Grundlage für die Bewirtschaftung von Stromverteilungsnetzen an einen Server weitergeleitet werden. Die Vorrichtung zur Umsetzung des Verfahrens schliesst eine befestigbare Manschette ein, in der über ihren Umfang verteilt mehrere Magnetfeldsensoren (8) angeordnet sind.
